User Exit

[Former Member]

In ME21/ME22N transaction, if the user creates PO for a material which is having stock already then I need to save the PO item with Qty = PO qty - Stock Qty . Pls tell me the User exit that can be used for this. I tried with MVME001(EXIT_SAPLEINR_003) but it is not getting saved. Kindly help.

Thank You.

HI,

Execute the below program by giving the Transaction code as the input parameter. It will give all the User Exits available for that Tcode.

REPORT YUSEREXIT .

tables : tstc, tadir, modsapt, modact, trdir, tfdir, enlfdir.

tables : tstct.

data : jtab like tadir occurs 0 with header line.

data : field1(30).

data : v_devclass like tadir-devclass.

parameters : p_tcode like tstc-tcode obligatory.

select single * from tstc where tcode eq p_tcode.

if sy-subrc eq 0.

select single * from tadir where pgmid = 'R3TR'

and object = 'PROG'

and obj_name = tstc-pgmna.

move : tadir-devclass to v_devclass.

if sy-subrc ne 0.

select single * from trdir where name = tstc-pgmna.

if trdir-subc eq 'F'.

select single * from tfdir where pname = tstc-pgmna.

select single * from enlfdir where funcname =

tfdir-funcname.

select single * from tadir where pgmid = 'R3TR'

and object = 'FUGR'

and obj_name eq enlfdir-area.

move : tadir-devclass to v_devclass.

endif.

endif.

select * from tadir into table jtab

where pgmid = 'R3TR'

and object = 'SMOD'

and devclass = v_devclass.

select single * from tstct where sprsl eq sy-langu and

tcode eq p_tcode.
